Abstract

Objectives

Guided implant systems can be used as a training approach for placing implants. This in vitro prospective randomized pilot study evaluated the learning progression and skill development in freehand placement of two implants supporting a three-unit fixed prosthesis on a simulation model among novice operators.

Material and Methods

Four senior dental students with no prior implant placement experience participated in the study. As a baseline, each student placed two mandibular and two maxillary implants by freehand technique on a simulation model. Sixteen consecutive guided placements using a static guide, dynamic navigation, and template-based guide followed totaling 32 guided implant placements into maxillary and mandibular models. Freehand implant placements before and after the various guided navigation attempts were compared to assess their impact on freehand skill. Metrics compared included surgical time, horizontal, vertical, and angulation discrepancies between the planned and placed implant positions measured on superimposed CBCT scans and analyzed with repeated measures regression with Tukey's adjusted pairwise comparisons (α = .05).

Results

Before training with guided techniques, the average baseline freehand implant placement took 10.2 min and decreased to 8.2 after training but this difference was not statistically significant (p = .1670) There was marginal evidence of a significant difference in the 3D apex deviation with an average improvement of 0.89 mm (95% CI: −0.38, 2.16, p = .1120); and marginal evidence of a significant improvement in the overall angle with an average improvement of 3.74° (95% CI: −1.00, 8.48, p = .0869) between baseline and final freehand placement attempts.

Conclusions

Within the limitations of this pilot study, guided implant placement experiences did not significantly benefit or hinder freehand placement skills. Dental students should be exposed to various placement techniques to prepare them for clinical practice and allow them to make informed decisions on the best technique based on their skills and a given clinical scenario.

引导式种植体植入学习经验对徒手技能的影响：试点研究

目的引导式种植系统可用作种植体植入的培训方法。这项体外前瞻性随机试验研究评估了新手操作者在模拟模型上徒手植入两个支撑三单位固定修复体的种植体的学习进展和技能发展情况。材料与方法四名没有种植体植入经验的高年级牙科学生参与了这项研究。作为基线，每位学生在模拟模型上通过徒手技术植入两颗下颌种植体和两颗上颌种植体。随后使用静态引导、动态导航和基于模板的引导连续进行了 16 次引导植入，在上下颌骨模型上共进行了 32 次引导植入。比较了各种引导导航尝试前后的徒手种植体植入情况，以评估其对徒手技能的影响。比较的指标包括手术时间、计划种植体位置和已植入种植体位置之间的水平、垂直和角度差异，这些差异是通过叠加 CBCT 扫描测量的，并通过重复测量回归和 Tukey 调整配对比较进行分析（α = .05）。结果在使用引导技术进行培训之前，自由种植体植入的平均基线时间为 10.2 分钟，而在培训之后则减少到 8.2 分钟，但这一差异没有统计学意义（p = .1670）。89 mm (95% CI: -0.38, 2.16, p = .1120)；基线和最终徒手置放尝试之间的总角度平均改善了 3.74° (95% CI: -1.00, 8.48, p = .0869)。结论在这项试验性研究的限制条件下，引导下种植体植入经验对徒手植入技能没有明显的益处或阻碍。口腔医学专业的学生应该多接触各种植入技术，为临床实践做好准备，并根据自己的技能和特定的临床场景做出最佳技术的明智决定。

期刊介绍： Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
